The solution is to add the following section in angular.json:
"optimization": {
"scripts": true,
"styles": {
"minify": true,
"inlineCritical": false
}
}
The section needs to be added in architect > build > configurations > production section. The section will look like this:
"configurations": {
"production": {
"budgets": [
{
"type": "initial",
"maximumWarning": "2mb",
"maximumError": "3mb"
},
{
"type": "anyComponentStyle",
"maximumWarning": "3kb",
"maximumError": "8kb"
}
],
"fileReplacements": [
{
"replace": "src/environments/environment.ts",
"with": "src/environments/environment.prod.ts"
}
],
"optimization": {
"scripts": true,
"styles": {
"minify": true,
"inlineCritical": false
}
},
"outputHashing": "all",
},
